Abstract

ABSTRACT Few researchers have presented solids friction factor correlations for the fluidized dense phase conveying of fine particles or powders. Pressure drop for conveying can be predicted using these correlations. These correlations predict the pressure drop with minimum error margin for a definite pipeline configuration or for some specific types of conveying materials. Few researchers have applied their correlations for different pipeline configurations (of different pipeline lengths or diameters) or different conveying materials to predict the pressure drop. In this paper, different solids friction factor correlations for the fluidized dense phase conveying have been considered which are available in the literature and the behaviour of these correlations have been studied under length scale-up or diameter scale-up conditions. It has been observed that only few correlations exhibit natural pressure drop variation with change in pipeline length or pipeline diameter.

流化密相输送中固体摩擦系数相关性的综述与分析
摘要很少有研究人员提出细颗粒或粉末流化密相输送的固体摩擦因子相关性。可以使用这些相关性来预测输送的压降。对于确定的管道配置或某些特定类型的输送材料,这些相关性以最小误差范围预测压降。很少有研究人员将它们的相关性应用于不同的管道配置(不同的管道长度或直径)或不同的输送材料来预测压降。本文考虑了文献中可用的流化密相输送的不同固体摩擦因子相关性,并研究了这些相关性在长度放大或直径放大条件下的行为。已经观察到,只有很少的相关性表现出自然压降随管道长度或管道直径的变化而变化。
